Answer:
<h2>158,400 J</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 4500 × 35.2 = 158400
We have the final answer as
<h3>158,400 J</h3>
Hope this helps you
The Bridge of San Luis Rey is the correct answer.
The Bridge of San Luis Rey is the most famous novel of American author and novelist Thornton Wilder. The novel won for him the Pultizar Prize as well. The novel basically examines the lives of the five persons who died due to bridge collapse in eighteenth century Peru and the priest interprets their stories to explain the working of divine providence.
Answer:
The angle of launch of the rubber band affects the initial velocity. The more the rubber band is stretched the more force it applies to return to equilibrium and the more kinetic energy that results in.
Answer:
Since the astronaut drops the rock, the initial velocity of the rock is 0 m/s
<u>We are given:</u>
initial velocity (u) = 0 m/s
final velocity (v) = v m/s
acceleration (a) = 1.62 m/s/s
height (h) = 1.25 m
<u>Solving for v:</u>
From the third equation of motion:
v²-u² = 2ah
replacing the variables
v² - (0)² =2 (1.62)(1.25)
v² = 1.62 * 2.5
v² = 4 (approx)
v = √4
v = 2 m/s
The speed of the rock just before it lands is 2 m/s
